Title: Ultrasonic cutting and sealing
Inventor: FLOOD GARY N
IPC: B29C65/50
Filed: 1985-06-28
Abstract: An ultrasonic seal and cut method and apparatus comprises an ultrasonic sealing and cutting station which includes a horn adapted to be resonant at an ultrasonic frequency and an oppositely disposed anvil having a sealing surface and a cutting surface. As sheet material is passed through the station, the sheet material is cut and sealed in a marginal region adjacent to the cut. A substantially thermoplastic filament, either monofilament or multifilament, is fed together with the sheet material through the station in a position to cause the filament to fuse with the material in the marginal region. The addition of the filament permits the ultrasonic seal and cut method to be used for sheet material having a relatively low thermoplastic fiber content, exhibiting an open mesh weave, or being made from natural fibers. <IMAGE>

Title: D.C.-D.C. converter
Inventor: ARMSTRONG DESMOND ROSS
IPC: H02M3/338
Filed: 1986-11-14
Abstract: In order that a d.c.-d.c. converter should draw very little current in the stand-by condition the converter oscillator (5) is of the blocking oscillator type and energises an inductance (8,9) during its unblocked periods, this inductance in turn supplying output terminals (3,4) via a rectifier circuit (6).

Patent GB-2193349-A (GB)
Title: Relief/safety valves
Inventor: LAMBURN LEONARD WILLIAM
IPC: F16K37/00
Filed: 1987-02-18
Abstract: A system is disclosed for monitoring/testing operation of the servo operation of a pneumatically assisted spring loaded relief and/or safety valve 1 without loss of supplementary valve member closure loading at 3A. This comprises shut off valves FIVA & B, 3 way cock TBB (to which a pump can be fixed), a number of pressure gauges for monitoring operation and a relay valve R35P to which the loading on upper chamber 3A is fed back to assist the biasing force acting in the closing direction of the relay. To ensure valve operation when signalled, but pilot activation fails to remove valve member supplementary loading, such pressure is fed back to the control diaphragm of the regulator supplying servo valve lift assisting pressure thus augmenting it's output pressure by a like amount. These pressures, lift inhibiting, and lift assisting, are equal and self cancelling, each applied to it's opposing actuator chamber. Valve lift assisting servo pressure is controlled by the preset spring loading of it's regulator. The pressure gauges, suitably located, demonstrate pressure changes during simulated servo cycle operations. The system also includes pilot valves 5A and 5B. <IMAGE>

Title: Circuit arrangement for producing a binary signal
Inventor: MURRAY BRUCE
IPC: H03K5/08
Filed: 1988-04-27
Abstract: A precoded duobinary signal is applied to first inputs of two voltage comparators (CP1, CP2) whose second inputs receive reference voltages appropriate to required slicing levels.

Title: Improving solubility by electrodialysis
Inventor: FERN W A
IPC: C09B69/02
Filed: 1988-06-20
Abstract: A process for improving the solubility of a salt of an organic ionic dye or fluorescent brightening agent (FBA) with a first counter-ion, by exchanging the first counter-ion for a second counter-ion giving a salt of the dye FBA with improved solubility which comprises submitting a first aqueous solution or slurry of the salt of the dye or FBA with the first counter-ion to ion-exchange electrodialysis in conjunction with a second aqueous solution of a salt of the second counter-ion whereby at least a proportion of the first counter-ion in the first solution is replaced by the second counter-ion. The process may be conducted in electrodialysis cell 8 which has a dye compartment 10, replacement ion compartment 12, waste solution compartment 14, and two electrode compartments 16 and 18. The compartments are defined by cation permeable membranes 20, 22, 24 anion permeable membrane 26 and the walls of the cell. The process is especially useful for improving the solubility of anionic dyes, which are generally produced on a commercial scale in the form of their sodium salts, by at least partial replacement of the sodium ions by lithium or quaternary nitrogen (i.e. ammonium or substituted ammonium) ions. Improved solubility allows the preparation of higher strength liquid forms of the dyes. <IMAGE>
